Abstract [en]

The purpose of the present study was to investigate long-term coital behaviour in women treated with cognitive behaviour therapy (CBT) for superficial coital pain and vaginismus. Data were taken from a questionnaire concerning long-term coital behaviour sent to 59 women who presented to Linköping University Hospital because of superficial coital pain, had been diagnosed with vaginismus, and had been treated with CBT. Data were also traced from therapy records: mean follow-up time was 39 months, the women had suffered for an average of almost 4 years, and required a mean of 14 treatment sessions. Forty-four of the 59 women returned the questionnaire, for a response rate of 74.6%. At follow-up, 81% of the treated women had had intercourse. A majority (61%) rated their ability to have intercourse without pain as 6 or higher (on a scale from 0-10), and 61% rated their ability to enjoy intercourse as 6 or higher (on a scale from 0-10). The proportion of women with positive treatment outcome at follow-up ranged from 81% (able to have intercourse) to 6% (able to have pain-free intercourse). An ability to have intercourse at end of therapy was maintained at follow-up. Two-thirds of the women reported high fulfillment of individual treatment goals. At follow-up, the women estimated a significantly higher self-worth as sex partners, and as women and human beings, than before treatment. Twelve per cent of the original sample had healed after a few assessment sessions and without treatment.

Abstract [en]

Vaginismus is a sexual pain disorder, where spasm of musculature of the outer third of the vagina interferes with intercourse. Vaginismus exists in two forms: total vaginismus, where intercourse is impossible, and the more seldom described partial vaginismus, in which intercourse is possible but painful.

The aim of the thesis was to develop a useful definition of partial vaginismus for both clinical and scientific purposes; to describe the prevalence of partial vaginismus among women with superficial coital pain; to report on symptoms and clinical findings in women with partial vaginismus; and to present treatment results for women with vaginismus.

In a clinical sample of 224 women with superficial coital pain, we found a great overlap of the clinical diagnoses of partial vaginismus (PaV) and vulvar vestibulitis (VVS) (nowadays called provoked vestibulodynia); 102 women had both PaV and VVS. All women with VVS had vaginismus. Partial vaginismus was more common in all our samples than total vaginismus.

sEMG of pelvic floor muscles was found to be of no value in distinguishing women with partial vaginismus with or without vulvar vestibulitis (PaV+/-VVS) (n=47) from each other or from an asymptomatic group (n=27).

Women with PaV+/-VVS (n=53) reported not only burning pain but also itch during a standardized penetration situation (sEMG of pelvic floor muscles), while asymptomatic women (n=27) did not. In most cases, the appearance of burning pain preceded the appearance of itch.

In a retrospective interview study, 24 women with PaV+/-VVS reported pain after intercourse more often than pain during penetration at the onset of the problem. When the women ceased having intercourse, both symptoms were equally common. Intensity of pain during penetration increased dramatically from very low at onset of the problem to very high when the women ceased having intercourse, while intensity of pain after intercourse was already high at onset of the problem and increased to very high when the women ceased having intercourse.

Pain after intercourse in women with PaV+/-VVS was described as burning and/or smarting and lasted in mean for two hours, while pain during penetration was described with words like sharp/incisive/bursting and lasted for one minute.

At long-term follow-up (more than three years) of a group of women treated with cognitive behaviour therapy for vaginismus (n=59, response rate 44/59 on a questionnaire), a majority were able to have and enjoy intercourse. The proportion of women with positive treatment outcome was, however, associated to the definition of treatment outcome. An ability to have intercourse at end of therapy was maintained at follow-up. Every tenth women with vaginismus healed spontaneously after thorough assessment.

Conclusion: Partial vaginismus was more common in our studies than total vaginismus, and all women with vulvar vestibulitis had partial vaginismus. Women with PaV+/-VVS reported not only burning pain during standardized penetration but also itch. When the problem started in women with PaV+/-VVS, pain after intercourse was more common than pain during penetration. Pain after intercourse was described as longlasting and burning and/or smarting, while pain during penetration was described as short and sharp/incisive/bursting. Long-term follow-up results of a series of women treated with CBT for vaginismus show good treatment outcome.
